JOSEPH LITTLETON DENNIS, OF ATLANTA, GEORGIA, ASSIGNOR OF ONE- HALF TOTOMLINSON F. BREWSTER, OF SAME PLACE.

BINDERY PASTING-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 481,258, dated August23, 1892. Application filed March 1.9, 1891. Renewed May 31, 1892.Serial No. 435,069. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, JOSEPH LITTLETON DENNIS, a citizen of the UnitedStates, and a resident of Atlanta, in the county of Fulton and State ofGeorgia, have invented certain new and useful Improvements in BinderyPasting-Machines 5 and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and t o lettersof reference marked thereon, which form a part of this specification.

This invention relates to machines for applying the glue or paste on theproper places and manner upon the fold of a pamphlet in binding same,the object being the improvement of the art to the extent of furnishinga durable machine which will properly perform the function desired andbe inexpensive to the user, the details of the invention beinghereinafter fully specified.

In the accompanying drawings, Figure l is an elevation of the devicelooking at the left side in Figs. 2 and 3, showing the elements in theirnormal position. Fig. 2 is a vertical cross-section through the entiredevice, the cut being to the right of the center of Fig. l, this figureshowing by dotted lines the position assumed bythe parts in applying theadhesive. Fig. 3 is an end elevation of the right end of Fig. l, furthershowing the elements therein shown. Fig. 4 is a detail in sectionthrough the frame, showing the glue-receptacle and means of suspendingsame, both ends being duplicate. Fig. 5 is a detail perspective view ofone of the paste-dipping plates and springs thereof.

In the drawings like reference-characters are employed in thedesignation of corresponding elements in all the views.

A is the base, upon which rest and are secured the uprights B. The baseA is preferably in the form of a table-top, upon which the work may belaid, as will be presently seen.

Journaled at each end to the uprights B, near their bottoms, is a shaftC, which is arranged by means of a weight-lever c or a spring and stopto remain normally in the position shown. Arms c are secured to saidshaft by the proper connecting device, the preferred form of which is asshown in Fig. l-that is, setting their lower ends in mortises andpivotally securing them therein. In order to be light and resilient,these arms are made of wood, although of course metallic arms wouldperform the function required, and are caused to stand apart byacross-piece c2, of wood or metal, the ends thereof entering notches c3in one side of each of the arms c. Attached to the distant extremitiesof these arms c and extending in a taut condition between them is a cordc4, of liber or metal, the former preferred, and to keep this taut andelastically so Vis the function of the resilient arms c and thecross-bar c2. Whentheshaft C is in the position shown in the drawing,these arms project approximately vertically therefrom in the specificconstruction shown. Projecting from the proper side of the shaft C isacam c5, over which passes the co1dc6,asshown, the end being secured inany suitable manner to the shaft O, near the base of said cam c5. By theoperation of this cam it will be seen that the initial movement of theshaft C on the depression by the foot of the treadle to which the cord cis secured will be slow, and all tendency of the centrifugal to throwthe glue will be obviated, the speed being increased and the force,hence, diminished at the latter end of the stroke to a degree that willnot spread the glue between the sheets already pasted, or unduly strainthe cord c4.

Suitably carried near the top of the frame is a glue or paste pot D, arecess d being provided in the frame for the flanges d of said pot. Atransverse pipe E, provided with jets c, delivers gas or inflammable oilunder the said potfor combustion in heating, and necessarily suitablecocks are thereto affixed for controlling said combustion. Burners ofAr- .gand or other suitable construction are preferable.

The shaft I1" is journaled on the frame near the glue-pot D and carriesone or more arms f, which arm or arms carry a cross-bar f', to which aresecured the removable dippingplates f2 by a spring-snap f3 thereon beingpressed over the said cross-bar. By reason of this removability of theplates it Ais obvious ICO arg

that various combinations of glued spaces may be laid upon the paper,the cross-bar f being provided with as many plates f3 in the properposition as are necessary to dip up and deliver glue to the cord c4 whenbrought into contact therewith. For actuating the shaft F it isconnected with the shaft C by pitman or otherwise, the preferable formbeing shown consisting of a strap or cord f". Owing to the arc passedthrough by the dipping plates being shorter than that of the arms c',the said plates will remain in the glue during the latter portion of thepassage downward of the said arms, which will keep said plates at alltimes heated and prevent any accretion of glue thereon and deliver theglue to the cord c4 in the same degree of liquidity.

The operation of this device is as follows: Suitable guides are set uponthe table A to bring a folding-point on the pamphlet to the point wherethe cord c4 will fall along said folding-point. The treadle is thencompressed and the cord laid along said folding-point by the partialrevolution of said arms carrying said cord, and, being released, saidarms will be drawn back by the weight on the shaft C. As the arms godown the glue-dipping plates descend into the glue, and as they comeback the said dipping-plates are lifted out of the glue and the cord islaid against said plates, after which the second folio is laid on top ofthe rst according to the guides and the arms andcord carried thereby areagain depressed, gluing the folding-point of the second folio andpressing said second folio against the glued portion of the first folio,thus insuring its adherence. The pamphlet is then completed in thismanner, and when thelast folio is reached it is not glued, but the firstfolio of the next pamphlet is laid on top thereof and the operationproceeded with.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In a device of the class specified, the combination of the shaft C,carrying-arms proj ecting therefrom, a cord secured at each end to oneof said arms at its distal extremity, means for forcing said arms apartfor the pur pose of tightening said cord, and means for supplying saidcord With paste, for the purpose specified.

2. The combination of a binding-cord, supporting-arms therefor, ar0ck-shaft to which said arms are secured, a glue-pot, a dippingplate c,means to swing the dipping-plate from the glue-pot into the path of thebindingcord, consisting of a rock-shaft and suitable platesupportingarms secured thereto, and means to operate said shaft, all substantiallyas described.

3. In a device of the class specified, the combination of the rock-shaftF, the carryingarms f, secured to said rock-shaft, the connectingcross-bar on the free ends of the carrying-arms, and the movable platesprovided with the hook-shaped springs, said plates being adapted to beremovably attached to the cross-bar, all substantially as described.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

JOSEPH LITTLETON DENNIS.
